【摘要】：目的探讨股动脉斑块声像特征诊断非ST段抬高型急性冠状动脉综合征(NSTE-ACS)的价值。方法选取冠心病伴颈动脉及股动脉斑块患者72例,分为NSTE-ACS组(n=42)和慢性心肌缺血综合征(CIS)组(n=30),行CEUS、三维超声及灰阶强度定量分析,检测斑块造影增强强度(EI)、斑块体积、形态特征及回声灰阶强度(EL)等参数并进行对比分析。结果 NSTE-ACS组斑块EI、形态不规则斑块比例高于CIS组,EL低于CIS组(P均0.05)。颈动脉和股动脉斑块EI、EL和形态分类均与NSTE-ACS具有相关性(P均0.05)。股动脉斑块EI、EL为NSTE-ACS的危险因素(OR=1.222、1.177,P0.05)。颈动脉斑块EI、EL诊断NSTE-ACS的曲线下面积(AUC)分别为0.801、0.757(P均0.001),股动脉斑块EI、EL的AUC分别为0.814、0.774(P均0.001)。结论股动脉斑块内新生血管、形态特征和内部回声均与NSTE-ACS存在相关性,且较颈动脉更强;多种超声技术联合评价股动脉斑块声像图特征有望成为预测冠状动脉斑块稳定性、筛查冠心病高危患者的参考指标。
[Abstract]:Objective to evaluate the diagnostic value of ultrasound features of femoral artery plaque in non-St segment elevation acute coronary syndrome (NSTE-ACS). Methods Seventy-two patients with coronary artery disease associated with carotid and femoral plaques were divided into two groups: NSTE-ACS group (n = 42) and chronic myocardial ischemia syndrome group (n = 30). CEUs, 3D ultrasound and quantitative analysis of gray scale intensity were performed. Morphological characteristics and echo gray scale (ELL) parameters were compared and analyzed. Results in NSTE-ACS group, the plaque EI and irregular plaque ratio were higher than those in CIS group (P < 0.05). The EIL and morphological classification of carotid and femoral plaques were correlated with NSTE-ACS (P < 0.05). EIN El of femoral artery plaque was the risk factor of NSTE-ACS. The AUC of EII-EL in diagnosing NSTE-ACS was 0.801 ~ 0.757 (P = 0.001), and the AUC of EII-EL in femoral plaque was 0.814 ~ (0.774) (P = 0.001). Conclusion the morphological features and internal echo of femoral artery plaques are correlated with NSTE-ACS and stronger than that of carotid artery. Screening of high-risk patients with coronary heart disease reference indicators.
